GEORGE F. BROIVN, OF PHILADELPHIA, PENNSYLVANIA,

COMBINED WASTE AND OVERFLOW TUBE FOR SANITARY STRUCTURES.

SPECIFICATION forming. part of Letters Patent No. 398,224, dated February 19, 1889.

Application filed June 3, 1887. Serial No. 240,166. (No model.)

To all whom it may concern:

Be it known that 1, GEoncE F. finown, a citizen of the United States, and a resident of Philadelphia, Pennsylvania, have invented certain Improvements in OmlYilDMl \Vaste and Overflow Tubes for Sanitary Structures, of which the following is a specification.

The object of my invention is to so construct the waste and standing overflow-tubes of wash-basins and like sanitary apparatus that all the working parts will be below the level of the slab or top plate, so that the surface of the top plate will be comparatively free, and so that, where desired, it may be made entirely free of any projecting fixture.

In the accompanying drawings, Figure 1 is a sectional perspective view of a wash-basin provided with my improved waste and over how. Fig. 2 is a sectional view of a portion of the basin and overflow, showing the valve of the overflow seated. Fig. 3 is a view similar to Fig. 52, with the overflow tube and valve raised. Fig. -.t is a sectional plan on the line 1 2,Fig.2. with a portion of the overflow-tube in outside view. when combining-spigots are used with the wash-basin; and Figs. 7, 8, 9, 10, and 11 are views of different forms of steadying devices which may be used in carrying out my invention.

When this device is used in connection with a washbasin, the bowl A has a recess, a, at The slab B, forming the top of the wash-stand, completely covers this recess, as shown in the drawings, and in the recess I place the combined waste and overflow tube 1), the object being to place it back of the line of the bowl, so that it is out of the way. In most wash-basins where this combined waste and standing overflow-tube is used all the operating mechanism is above the slab and the tube is suspemled from this mechanism. The main object of my invention is to place the operating devices which raise the tube below the level of the slab, so that very little, it any, projection necessary on the surface.

Referring to Figs. 1, 2,3, l, and 5 of the accompanying drawings, D is the overflow-tube, having the usual valve, (1, which is adapted Fig. 5 is a section of the valve-seat Fig. (3 is a view of the preferred form I to the seat in the waste-pipe E,secured to the bowl by means of the nut F. Below the valve (7 is an extension, (1, having suitable openings, through which, when the valve is raised to the position shown in Fig. 3, the water is allowed to flow into the waste-pipe, and on the lower edge of this extensionare legs e e,whieh bear against the faces of cams ff, formed in or secured to the waste-pipe hen the tube D is turned, the legs c ride on the faces of the cams, and the tube with its valve is raised until the legs come onto the fiat rests f, as shown in Fig. 3, allowing the water to escape from the bowl. raised by simply turning the tube in the direction of the arrow, Fig. 4-, and lowered by turning it in the reverse direction, so that by providing the tube D with a handle,D, at its upper portion, as shown in Fig. 0, the whole device may be arranged below the level of the slab of the wash-stand, and combining-faucets can be used'z'. a, faucets in which two pipes provided with two valves combine together into one outletas these valves are generally situated so near together that it is impossible to provide any lifting attachment for the overflow-valve that would extend up above the slab of the wash-stand; but where the ordinary faucets are used I prefer to extend a guiderod, G, up through the slab, it having its bearings in and resting upon a sleeve, H,

l l l l secured to the slab by means of a nut, 71, as shown in Figs. 2 and 3.

The guide-rod (Jr is provided at its upper end with a suitable hand-wheel, 2', and has a squared lower portion, g, which is preferably 1 connected to the main portion of the rod by means of a universal joint, g. This squared portiml enters into a square orifice in a cross- 3 bar, 7', in the top of the tube D, so that the 3 tube D is free to slide on the squared portion l of the rod, but must turn with it, so that when the handle 1'. is turned by the operator the tube D, owing to the legs e acting upon the cams f, will be raised to the position shown in Fig. 3, and will rest in this elevated position, with the legs supported on the rests f, until the hand-wheel of the guide-rod G is turned back again, when the tube will drop and the valve be closed. It will be understood that this guide-rod G does not lift the The tube D is thus valved tube D, but merely turns it, the tube D being lift-ed entirely by the cams f. The rod G acts as a guide-pin, so that the tube D when in its raised position will not be liable to topple over.

I provide the universal connection g on the rod for the purpose of allowing the valve (1 of the tube D to readily seat itself when closing, as the bowls are not always in proper relation to the slabs, and this universal connection will accommodate itself to any irregularities caused by the setting. \Vhen it is required to remove the overflow-tube D from the basin, the rod (l is simply raised clear of the upper portion of the tube, after which the tube can be readily removed for eleanin and other purposes.

In the modification illustrated in Fig. 7 I have shown this rod as a plain cylindrical pin, G, extending into the orifice in the cross piece j and acting only as a guide, the tube being turned by a handle, I). In Fl 8 I have shown this guide-pin (l extending up from a crows-toot on the outlet-tube E, serving the same purpose as the pin. in Fig. 7, only at. the bottom of the tube l) instead of at the top. In Fig. (i I have shown, instead of the central guide-pin, G, a tubular guide, G bearing against the outside of the tube D. This guide is held in position on a standard, M, extendin upward from the base or outlet pipe E. This tubular guide G is detachably secured to the standard, so that it can be readily removed when the stand-pipe is to be re moved from the basin. In Fig. 9 I have shown this guide G2 provided with and supported on downwardly-extending arms in, fittin into orifices in suitable lugs on the waste-tube D. In Fig. 10 I have shown the cams f on the guide G projecting from the crows-foot in the waste-pipe E, the legs 6 being formed in or secured within the tube D. By this arrangement the waste water and sediment do not wash over the cam.

In Fig. 11 I have shown the guide-pin G with. a head, a, which is swiveled in a pocket, 71, under the slab cannot fall over when in its raised position. \Vhen it is required to remove the tube, the

It will be understood that my invention may be attached to bath-tubs and other sanitary apparatus as well as wash-basins.

I claim as my invention 1. The combination,in a wash-basin or like receptacle having a top slab overhanging said basin, of a combined waste and overflow tube, D, with an operating-cam for the tube, said cam. being below the top of the tube, all substantially as set forth.

2. The combination, in a wash-basin or like receptacle, of the overhanging top slab, the J the same with a jointed rod squared at its lower end to fit into a squared opening in the tube and extending above the level of the slab, and provided with a suitable handle, whereby on turning said handle the tube will turn with and slide on the jointed rod, substantially as described.

5. The combination of a waste and overflow tube having legs, a guide for said tube, and an outlet-tube provided with cams forming bearings for said legs, whereby the tube is raised when it is turned, as and for the purpose set forth.

6. The combination of a waste and overflow tube having legs, a waste-pipe provided with cams forming bearings for said legs, and a removable guide tor the tube, substantially as set forth.

7. The combination of the waste and overflow pipe and an operating-cam below the top of the pipe upon which said pipe is supported,

3 but from which it is removable, all substantially as specified.

In testimony whereof I have signed my name 1 to this specification in the presence of two subhead a can be readily removed from the pocket l n and replaced at will.

In place of the hand-wheel 1: of the rod G a I scribing witnesses.
